城市中心区是城市最繁荣的地区,在“三期叠加”的时代,增量不足、功能隔阂、空间失衡成为制约城市中心区发展的主要瓶颈,挖掘城市中心区存量空间,整合城市功能结构是城市中心城区规划策划重点.文章将沈阳北站北广场47ha的用地定位为皇姑红钻区,通过对红钻区的发展背景和发展失衡的原因进行深入分析总结,结合红钻区的发展现状,立足城市中心区发展趋势和本区的发展期望,提出产业一体化、空间一体化和政策一体化的规划策划
新型城镇化进程中,应当充分重视和发挥中小城市尤其是经济社会发展有较强优势的中小城市对农业转移人口的吸纳作用.农业转移人口市民化,要求政府和企业具备相应的服务能力,并承受相应的城镇化成本.对农业转移人口市民化成本分担的测度,有利于为政府间事权和支出责任的划分提供决策依据,保障新型城镇化建设工作的顺利开展.仅以国家第二批新型城镇化试点城市内蒙古自治区和林格尔县为例,在2016-2020年试点期内,如需
开发区作为我国重要的城乡空间组成单元,响应、落实和运用现有国家城镇化制度,推进开发区产城融合发展,是新型城镇化建设的客观要求.研究开发区产业发展与城市功能建设的进程,是探讨产业开发区“产城融合”的关键所在.本文以呼和浩特市盛乐开发区为例,从“产”和“城”两个角度进行定量分析,其中从产业集约化程度、产业结构、有效劳动率和土地利用率四个方面佐证产业发展情况;通过公共服务设施的耦合度和协调度两个方面分析

糠醇(FA)是一种重要的精细化学品,在工业中有着广泛的应用[1],一般通过糠醛(FAL)加氢制得.在已报道的加氢反应条件下,糠醇易于发生多种副反应,如深度加氢生成四氢糠醇及自聚[2].本文报道了不同Zr-MOF材料(UiO-66,UiO-67,Zr6-NDC,MIL-140A,MIL-140B和MIL-140C)负载Ru纳米粒子对糠醛加氢选择催化生成糠醇的反应性能[3].
